README
<div align="center"> # 🧰 skill-kit ### The skill-testing workshop, packaged as a Claude Code plugin **Author, evaluate, security-review, and autonomously improve Claude Agent Skills — in any project, with evidence, not vibes.** [](https://github.com/mjenkinsx9/skill-kit/actions/workflows/harness.yml)      [](LICENSE) </div> --- The core idea: **a skill is only as good as the evidence behind it.** skill-kit brings the full evaluation stack from the [skill-testing](https://github.com/mjenkinsx9/skill-testing) dev-bench to any project as an installable plugin — a 21-check static harness, a live behavioral check, empirical trigger measurement, a blind value-add baseline, and an autoresearch loop that iteratively tightens a `SKILL.md` and keeps only the changes that score better. ## ✨ What's inside | Layer | Tool | What it proves | |---|---|---| | 🧹 **Static** | `check-skill` | The skill is *well-formed* — 21 checks: frontmatter, naming, trigger language, secret & security-smell scans | | ⚡ **Behavioral** | `behavioral-check` | The documented commands *actually run* against the real system today | | 🎯 **Empirical trigger** | `trigger-accuracy` | The skill *really fires* on its positive prompts and declines its negatives | | ⚖️ **Value-add** | `value-add-test` | The skill *beats the cold model* in a blind head-to-head | | 🔄 **Autoresearch** | `improving-skills` | Iterative modify → score → keep-or-revert loop that tightens an existing SKILL.md | | ⚓ **Goal anchoring** | `goal-new-skill` · `goal-improve-skill` | Skill work is driven by a measurable end state, not vibes | The harness is self-tested (9 pathological fixtures + 34 pytest tests) and CI enforces zero FAILs *and* zero WARNs on the shipped skills, on every push and PR. ## 🚀 Install Inside Claude Code, on any machine: ``` /plugin marketplace add mjenkinsx9/mjenkins-toolbox /plugin install skill-kit@mjenkins-toolbox ``` Update later with `/plugin update skill-kit`. Because a plugin's `bin/` joins the Bash `PATH`, every helper is callable by bare name in any repo. skill-kit also installs on Copilot CLI, Codex, Cursor, and Gemini — see [Multi-harness support](docs/04-harnesses.md). ```bash # Lint a skill directory (or a SKILL.md directly) — exit 0 iff zero FAILs: check-skill .claude/skills/my-skill ``` ``` /skill-kit:improving-skills .claude/skills/my-skill/SKILL.md ``` ## 📚 Documentation Full guides live in [`docs/`](docs/). Start with the overview, then dive into the section you need. | Doc | Description | |---|---| | [Overview](docs/01-overview.md) | What skill-kit is, the core idea, and the evaluation stack | | [Installation](docs/02-installation.md) | Marketplace install, the `bin/`-on-`PATH` convention, requirements | | [Usage](docs/03-usage.md) | The `bin/` commands, slash commands, and the improving-skills scoring loop | | [Multi-harness support](docs/04-harnesses.md) | Per-harness status, manifests, and install notes | | [Repository layout](docs/05-layout.md) | Map of manifests, helpers, commands, skills, and tests | | [Testing the tests](docs/06-testing.md) | Self-tests + pytest, and the relationship to skill-testing | Full documentation map: [docs/README.md](docs/README.md) ## 📄 License [MIT](LICENSE) © 2026 Mike Jenkins · [Security policy](SECURITY.md)
